Neck line filler is an injection of soft hyaluronic acid filler directly into horizontal neck creases, often called necklace lines, to smooth them from beneath. At Yaan Clinic in Gangnam, Seoul, neck line treatment is a multi-layer approach that combines HA neck filler, PDRN (salmon DNA) for skin regeneration, and neck-line laser energy delivered to the SMAS layer for tightening.
Yaan's doctors presented their neck-wrinkle filler approach, called Belle Neck, at the 2024 Korean Association for Laser, Dermatology, and Trichology Spring International Scientific Forum.
What are neck lines and why do they form?
Neck lines are horizontal creases that run across the front of the neck, sometimes called necklace lines or tech neck. They form from repeated bending, thin neck skin, loss of collagen and elasticity with age, and genetics. Many people notice them earlier than facial wrinkles.
Neck skin is thinner than facial skin and has fewer oil glands, so it shows aging sooner. Looking down at phones and screens folds the same lines thousands of times a day. Yaan's FAQ addresses why the neck often ages faster than the face, and also notes that horizontal lines and vertical bands are different problems. Vertical bands usually come from the platysma muscle, while horizontal lines are creases in the skin. For a full overview of the causes, read our guide to neck lines and crepey neck skin.
How does Yaan Clinic's neck line filler work?
Yaan treats neck lines in three layers at once: soft HA filler fills the crease itself, PDRN supports skin regeneration, and neck-line laser energy targets the deeper SMAS layer for tightening. Each layer addresses a different cause of the line.
| Layer | What Yaan uses | What it does |
|---|---|---|
| The crease | Soft hyaluronic acid neck filler | Fills the groove from beneath for a smoother surface |
| The skin | PDRN (salmon DNA) | Supports regeneration and skin quality |
| The support layer | Neck-line laser energy to the SMAS | Tightens to reduce laxity |
Treating only the crease can leave thin, loose skin untreated, while treating only skin quality may not soften deep grooves. Combining all three is designed to give a smoother, firmer neck with natural movement.
What happens during neck line filler treatment?
After a consultation, numbing cream is applied. The doctor then injects small amounts of soft filler along the lines, adds PDRN, and treats the neck with laser energy, adjusting the plan to the depth of your lines.
- Consultation and assessment – the doctor checks the depth and number of lines, skin thickness and elasticity.
- Numbing – numbing cream is applied for comfort.
- Filler – soft HA filler is placed precisely along each horizontal line.
- PDRN – PDRN is injected to support skin regeneration.
- Laser tightening – neck-line laser energy is delivered to the SMAS layer.
Good to know: Yaan Clinic does not publish a fixed procedure time, downtime or duration for neck line filler. As general guidance, small bumps, redness or mild bruising along the lines are common for a few days. Your doctor will confirm what to expect.
Is one session of neck line filler enough?
It depends on how deep the lines are. Yaan Clinic's FAQ addresses this question directly: shallow lines may improve well after one session, while deeper, long-standing lines may benefit from more sessions. Results vary between individuals.
Yaan also notes the benefit of early treatment. Lines that are treated while still shallow are typically easier to improve than deep grooves that have been present for many years. Yaan shares before and after cases at two months, but every neck responds differently, and your doctor will set realistic expectations.
Will my neck look stiff after filler?
No, that is not the goal. Yaan Clinic's FAQ addresses natural movement: soft filler is placed in small amounts along the lines so the neck can bend and turn normally. Too much or too firm a product is what causes stiffness or visible lumps.
Choosing a soft, thin filler designed for superficial areas and using a light hand are key. Yaan states that it uses genuine products in the correct dosage; see genuine products and safety.
Neck line filler vs other neck treatments
Filler is best for visible horizontal creases. For overall neck laxity without deep lines, energy-based tightening or skin boosters may be enough, and many patients combine approaches.
| Treatment | Best for | Notes |
|---|---|---|
| Neck line filler (HA + PDRN + laser) | Distinct horizontal necklace lines | Yaan's multi-layer approach |
| Skin boosters | Thin, crepey skin and fine lines | Improves skin quality; less effect on deep grooves |
| Sofwave | Fine lines and loss of firmness, including the neck | Ultrasound tightening; prices published by Yaan |
| Other skin tightening | General neck and jawline laxity | RF, HIFU and microwave options |

Who is a good candidate for neck line filler?
Good candidates are adults with visible horizontal neck lines or necklace lines, with or without mild loss of elasticity, who want a non-surgical improvement. People with significant loose skin or strong vertical bands may need other or additional treatments.
Neck filler may not be suitable during pregnancy, with active skin infection on the neck, or for certain medical conditions. Your doctor will confirm suitability at consultation. Explore all filler areas in our dermal filler guide.
For international patients: Small bumps along the lines are usually easy to hide with a scarf or high collar while they settle. Book early in your trip so the doctor can check the result, and ask whether a second session should be planned for a future visit. Read your first visit to prepare.
Frequently asked questions
Is one session of neck line filler enough?
It depends on line depth. Yaan Clinic's FAQ explains that shallow lines may improve well after one session, while deeper, long-standing lines may need more. Results vary between individuals, and your doctor will recommend a plan after assessing your neck.
Will I still be able to move my neck naturally?
Yes. Yaan Clinic uses small amounts of soft filler along the lines so the neck bends and turns normally. Stiffness or lumps usually come from too much or too firm a product, which careful technique and product choice are designed to avoid.
Why does my neck look older than my face?
Neck skin is thinner than facial skin, has fewer oil glands and folds constantly when you look down. Yaan Clinic's FAQ notes that the neck often ages faster than the face, which is why lines can appear early even when the face still looks youthful.
Does neck filler treat vertical neck bands?
Not usually. Yaan Clinic's FAQ distinguishes horizontal neck lines from vertical bands. Filler is aimed at horizontal creases in the skin, while vertical bands typically come from the platysma muscle and need a different approach discussed at consultation.
Is it better to treat neck lines early?
Yaan Clinic notes a benefit to early treatment. Lines treated while still shallow are generally easier to improve than deep grooves that have been present for many years, and may need fewer sessions to soften.
How much does neck line filler cost at Yaan Clinic?
At Yaan Clinic, neck line filler costs ₩390,000 per line. The total depends on the number of lines and sessions and is confirmed at consultation. International patients pay the same price as Korean patients.
